Glasgow City Mission said it would extend its opening hours to cope with the rising demand and would also offer clients help with managing money, accessing college courses and cooking healthy meals.
"As changes to state welfare begin to bite, we're finding more and more people are coming to us in desperate need of food," said Grant Campbell, the charity's chief executive.
"We've seen requests for food parcels jump from three or four a week to more than a dozen a day. Sometimes it is social work departments or other agencies acting on behalf of their client; on other occasions clients will visit us or phone us direct after being told by their job centre to try us for food, energy cards or even crisis loans.
"Sometimes it is an individual. Other times it is a single mother with four or five children to feed. While we can't issue money or energy cards, we can help with emergency food."
From today the service will operate every Monday, Wednesday and Friday, from 12 noon to 3pm from its Crimea Street premises.
